Step one: we’ve got a Python script hammering /api/v2/analytics/conversations/details via PureCloudPlatformClientV2. Token’s valid for 30 mins. We’re expecting the SDK to auto-refresh, but the batch job hits a 401 Unauthorized at iteration 287. Docs claim refresh_token flow is built-in, but nothing’s happening. Init looks standard: client = PureCloudPlatformClientV2(client_id, client_secret). Step two: we’re looping 500 requests. Callback never triggers. Checking the wire logs.
